You're right about the ::init() exit, that was a copy/paste oversight.

Is there something like QString -= extension or do I have to make something up myself with lastIndexOf and whatsmore?

As a result, all applications that propose to move things they manage to the wastebin (Dolphin, but also digiKam) will store those items in a place that has no particular meaning on OS X, and that will thus tend to fill up.

Files deleted from other volumes end up in `/Volumes/volName/.Trashes/uid`, where volName is the volume name (regardless whether it's an external or a remote drive; only mounted NFS shares are handled differently) and uid the numerical user id. Permissions on `.Trashes` are the same as those expected by KDE.
